Beyond products: new strategic imperatives for developing competencies in dynamic environments

Strategy research has often taken a product-centered perspective. When firms compete in environments characterized by accelerating product life cycles, mass customization, and technological discontinuities, a product-centered perspective on strategy may help explain a firm’s current competitive advantage. However, this perspective adds little guidance in making strategies that create competitive advantage in the future. In this paper, we present a perspective in which dynamic environments require firms to focus on (1) building market-driven, technological, and integration competencies, not a stream of product improvements, and (2) decoupling these competencies from current products in order to create and exploit new opportunities. We discuss the perspective of products as a temporary integration of market and technology trajectories. Research propositions are presented and future implications are discussed.     

Demanding work schedules and mental health in nursing assistants working in nursing homes

Nursing home assistants have physically and emotionally challenging jobs, and they often work demanding schedules in order to provide 24-h care. While the physical effects of demanding work schedules have been studied, little is known about the impact on mental health. This study explored the relationship between demanding scheduling variables and mental health indicators of depression, anxiety and somatization. A cross-section of 473 US female nursing assistants working in nursing homes was surveyed. Work schedule characteristics included shiftwork, hours per day and week, days per week, number of weekends per month, number of double shifts per month, breaks, and number of jobs worked. Working two or more double-shifts per month was associated with increased risk for all mental health indicators, and working 6–7 days per week was associated with depression and somatization. There was a trend for increasing odds of adverse mental health with increased numbers of demanding work schedule factors. The odds of depression was increased four-fold when working 50+ h/week, more than two weekends/month and more than two double shifts/month. Providing work schedules that are less unhealthy may have implications for both worker retention and the quality of care delivered to nursing home residents.     

Adolescent Transitions to Young Adulthood: Antecedents,Correlates, and Consequences of Adolescent Employment

The antecedents, correlates, and consequences of adolescent employment were investigated in a sample of 251 low‐income, African American youth that were followed since birth. The youth (age: M at preschool = 4.89, SD= .70; M at adolescence = 16.44, SD= .66; M at transition to adulthood = 19.36, SD= .76; and M at early adulthood = 27.67, SD= .75) were the firstborn children of African American teenage mothers who gave birth in Baltimore in the 1960s. Analyses examined the antecedents and correlates of age of entry into employment and stability of employment during adolescence. The associations of adolescent work experiences with subsequent adult education and employment outcomes also were considered. Findings indicate that among this sample of low‐income, African American youth, those who repeated a grade in school during middle childhood were more likely to enter the workforce at later ages than their peers who did not repeat a grade. The small subset of adolescents who never worked (n= 12) appear to be markedly more disadvantaged than their peers who worked. At the transition to adulthood, adolescents who entered the workforce earlier were more likely to complete high school than their peers. In addition, stable employment during the adolescent years had more beneficial effects on young men's chances of attending college than young women's postsecondary education. This pattern of findings is consistent with ethnographic accounts of adolescent employment among poor, minority, urban youth.     

Welfare and Work: Complementary Strategies forLow‐Income Women?

We examine the effects of mothers' strategies of combining employment and welfare receipt during the first 3 years of their child's life on the child's cognitive development, behavior problems, and home learning environment at ages 5 to 6. We compare the child outcomes of those mothers who were continuously employed and received no welfare with (a) those who worked some or all of the 3 years and also received public assistance and (b) those who were totally dependent on public assistance. We studied children in single‐parent families (N= 1271 ) living below 200% of the poverty threshold using data from the National Longitudinal Survey of Youth—Child Supplement. No negative association was found on most child outcomes with a mother's employment whether or not it was combined with public assistance. However, mothers' not working at all and receiving financial support solely from AFDC was associated with negative child outcomes. We discuss the implications of these findings for the possible effects of the new welfare laws on families and young children.     

Coparenting and nonresident fathers’ involvement with young children after a nonmarital birth

We use data from the Fragile Families and Child Wellbeing Study to investigate the association between coparenting quality and nonresident fathers' involvement with children over the first five years after a nonmarital birth. We find that about one year after a nonmarital birth, 48% of fathers are living away from their child, rising to 56% and then to 63% at three and five years, respectively Using structural equation models to estimate cross-lagged effects, we find that positive coparenting is a strong predictor of nonresident fathers' future involvement, whereas fathers' involvement is only a weak (but significant) predictor of future coparenting quality. The positive effect of coparenting quality on fathers' involvement is robust across several techniques designed to address unobserved heterogeneity and across different strategies for handling missing data. We conclude that parents' ability to work together in rearing their common child across households helps keep nonresident fathers connected to their children and that programs aimed at improving parents' ability to communicate may have benefits for children irrespective of whether the parents' romantic relationship remains intact.     

Models of accepting an early retirement incentive

The presence of special early retirement incentives has changed the work environment for older workers. It is of interest to know how existing models of the timing of the pension acceptance decision function in an incentive environment. Furthermore, it is of interest to note the similarities or differences between males and females with regard to retirement behaviors. In this study, a basic utility maximization model, an expanded model, and an interactive model are applied to the acceptance of an early retirement pension incentive; probabilities of acceptance range from .18 to .39. Acceptance behavior without the incentive is simulated, with probabilities of acceptance ranging from .11 to .33. Addition of a set of socioeconomic and psychological variables and a vector of interactive variables is found to improve the basic model.The author would like to thank W.

Citizenship and culture: the role of disabled people in Navajo society

Cultural constructs of disabilities can vary from one culture to another and significantly affect how the individual with disabilities is perceived, accepted, and accorded citizenship rights and responsibilities. This anthropological study of Navajo individuals with disabilities investigates these cultural constructs in a non-Western society from the perspective of the Navajo community members. Factors analyzed include child-rearing practices, the Navajo concept of childhood, and Navajo notions of health and unwellness. Historical attitudes toward disabled people are also explored, as well as changing attitudes due to the influence of Western biomedical explanations and interventions.     

The Association of Couples’ Relationship Status and Quality With Breastfeeding Initiation

Using data from the Fragile Families and Child Wellbeing Survey (N= 3,567), we examine the links between relationship status, relationship quality, and race and ethnicity in breastfeeding initiation. We consider four relationship types: married, cohabiting, romantically involved but not cohabiting (termed visiting), and nonromantically involved mothers. We find that even after adjusting for a wide range of sociodemographic factors, married mothers were more likely to breastfeed than unmarried mothers and that racial and ethnic differences in breastfeeding do not result from differences in marriage rates. Among unwed mothers, paternal provision of money or other assistance during pregnancy decreases the likelihood of breastfeeding. We conclude that relationship status, above and beyond demographic characteristics, is an important correlate of breastfeeding.     

Changing American home life: trends in domestic leisure and storage among middle-class families

This study of middle-class American families draws on ethnography and urban economic history, focusing on patterns of leisure time and household consumption and clutter. We trace how residential life evolved historically from cramped urban quarters into contemporary middle-class residences and examine how busy working families use house spaces. Our ethnographic sample consists of 24 Los Angeles families in which both parents work full time, have young children, and own their homes. Formal datasets include systematically timed family uses of home spaces, a large digital archive of photographs, and family-narrated video home tours. This analysis highlights a salient home-storage crisis, a marked shift in the uses of yards and garages, and the dissolution of outdoor leisure for busy working parents.
